@JohnDuffield re too users list: you've answered two questions using accepted physics (these got you a lot of rep), the other answers have been consistently downvoted

So your rep position does not lend any credibility to your pet theories, sorry.

If JR told us electrons are 511keV photons we wouldn't believe him either.

yuggib

For example, Dirac's wave equation that you cite above is intended to be an equation to describe, roughly speaking, the evolution in time of the probabilistic description (the wave is a "wave of probability" in very rough terms) of a massive spin-1/2 particle. With that interpretation, it gives predictions that are in very good agreement with observations up to a certain precision; then it is not correct anymore (and you need another theory to better fit those more precise observations).

If you want to give to Dirac's equation another interpretation (as a concrete wave describing a force field, or whatever) you have to be able to produce predictions that fit with your interpretation and the related experimental evidence. But those predictions have to be testable, i.e. numerical, and therefore a certain mathematical apparatus is needed.

Numerical analysis stuff: Pretty ribbon looking diagram

initial condition: $y=x^3$, iterative function $\sin(y)$

Fixed points are those that intersect the x axis
The density of the rainbow gradient lines give the rate of convergence to the fixed point (the more spaced out, the faster the convergence)
The underlying code need to be further refined before it can be applied to the logistic map

lol even yuggib can't resist

John Duffield

@yuggib : we have people here who dismiss those experimental facts because they don't square with something they've been told. And then they have to gall to refer to them as "your pet theories". I didn't invent electron diffraction. It wasn't me who came up with spherical harmonics. I didn't write the Wikipedia atomic orbitals article that said electrons exist as standing waves.

yuggib

@Danu I succeeded for so long...

Danu

All the lols

0celo7

@JohnDuffield Is electron = 511keV photon an established experimental fact?

We should put up a straw poll and see how many people agree.

13:35

@0celo7 : pair production and annihilation are experimental fact. So is electron diffraction and the wave nature of matter. Go read the Wikipedia atomic orbitals article: "The electrons do not orbit the nucleus in the sense of a planet orbiting the sun, but instead exist as standing waves." And don't blame me if that doesn't square with some tosh you've been taught about the electron being a point-particle.

0celo7

@JohnDuffield You're avoiding the question.

John Duffield

I'm not avoiding anything. You are.

0celo7

Show me that electron = photon

You make this claim.

You have the burden of proof.

Show me how an electron gets it charge from the photon.

John Duffield

I don't make that claim. A photon propagates linearly at c. An electron doesn't. Now go and look at that evidence instead of dismissing it. What do you think happens in pair production? Magic?

0celo7

You don't make this claim?

Q: The electron is a 511keV photon going "round and round." How does this work?

I'm curious about the properties of the electron as given in this PSE post. I always thought the electron was an excitation in the electron field. Apparently that's not true and it is a photon going round and round in a Dirac's belt configuration. I have some questions regarding this: 1) How doe...

@JohnDuffield Please answer my question now.

Hmmm... too broad or non-mainstream, which one to choose.

0celo7

This is completely mainstream.

@0celo7

@ACuriousMind got me thinking, how does electric charge happen in string theory anyway

does it have to do with the U(1) gauge theory or something

@Huy title says it all

user 536231

Reminds me of some older posts having an absurd claim about someone getting hit by a high voltage line that arced when.. dont remember.. someone took a photo with a flash or something.

John Rennie

@Ocelo7: that is a frankly contemptible question. It's not a question but an attempt to call out another site member. Whatever your views on that site members posts this is not the way to air them.

We don't do public shaming here. Not under any circumstances.

If you don't like someone's post then downvote it, then go home and get a life.

0celo7

@JohnRennie He told me to ask a question, I did.

John Rennie

16:32

That's not an excuse.

0celo7

I see no reason for an "excuse" for anything.

John Rennie

Because someone asks you to behave like an arse is a poor reason for doing so

He refused to answer my question any other way. I still don't see the issue.

I think he's misunderstanding the situation

he does not visit the chat

he's telling me how to measure spin using Stern-Gerlach

so it is comprehensible

ok what

now I'm legitimately confused

@Huy lemme know if you have any more questions about the mouse

Danu

16:44

@yuggib The word you're looking for is "understandable"

(it's not exactly the same thing)

yuggib

@Danu maybe you're right... :P

Danu

It's a tiny difference

0celo7

Danu is right, like always

Danu

Yet comprehensible sounds really out-of-place in that sentence

0celo7

can confirm, am native

Danu

16:45

@0celo7 I like this way of thinking

yuggib

I know, but it is a saxon difference

damn saxons...

0celo7

saxon difference?

yuggib

proper of the saxon roots of english language

0celo7

for the record, does anyone besides JR think that question is completely out of line?

Danu

I agree that, without the context of chat, it seems that way.

But given the extraordinary situation that has been going on here before, with many attempts to seriously understand what JD is on about, with him refusing to answer except through the main site, I don't think it's so bad.

Still quite edgy, so to say.

yuggib

16:49

And it is a bit sarcastic, probably...but I agree with @Danu

0celo7

it was designed to be snarky

should I try to rephrase?

this boils my blood: people who don't say "et cetera" but some version of "ec sedra"

yuggib

well you cannot make the question as "only answerable by john duffield"

0celo7

did anyone read Timaeus' answer? I don't think he understands JD's claim

Danu

@0celo7 That's pretty normal in the US, innit?

ACuriousMind

@0celo7 I don't think anyone does

I'd love to watch this play out, but I gotta run

How does a massless photon turn into a massive electron? It's just E=mc². See Einstein's 1905 paper where he says "if a body gives off the energy L in the form of radiation, its mass diminishes by L/c²". If you trap a massless photon in a gedanken mirror-box, the mass of the system is...
